The U.S. Department of Agriculture made the announcement Monday. The Portland Press Herald reports (http://bit.ly/1LbCO9L ) the frozen chicken affected by the recall was produced between Feb. 17 and May 20 and distributed throughout the United States and Canada.

Monday's recall is an expansion of a July 2 recall of 58,000 pounds of food. That was prompted by six illnesses in Minnesota and Wisconsin. Two more patients have been identified since then.

Barber is a division of AdvancePierre Foods Inc. A spokesman for the company says Barber is collaborating with the USDA to change production practices to reduce salmonella.
